Arsenic variability in water-supply wells

The USGS, in cooperation with the Town of Seabrook, New Hampshire and a private well owner, is assessing the variability of arsenic over multiple time scales. A network of three wells is being used to monitor changes in arsenic, arsenic species, a host of other chemical constituents, and the distribution of ages of groundwater entering the wells. The wells—one domestic bedrock aquifer well,...
